[Samba] ADS domain member: winbind fails

[Stefan G. Weichinger]

I am trying to set up winbind on a ADS domain member server.

The join works OK, but winbind simply fails to start.

see config and logs below, I am scratching my head.

Why does it "contact" a domain called "MAIN" ? that is the hostname of 
that server, not the domain name!

would be nice to get a quick reply, I am at the customer and this should 
work asap ....


Thanks!
